SAFETYDEVICE FOR AUTOMOBILES.

Application file cl september '12, 1925. Serial Np. 56,054.

To allwhom it may concern:

Be it known that I, NEAL ERASTUS WOOD, a citizen of the United States, residing at Chanute, in the county of Neosho andSt-ate 'of Kansas, have invented certainnew and useful Improvements in Safety Devices for Automobiles, of which the following is a specification.

This invention relates for use in connection with clutch pedals of cars of the Ford type, and has for its object to provide, in a mannerfas hereinafter set forth, a clutch pedal safety device adapted to vbe actuated on the application of the brake pedal of the car for the, purpose of arresting movement of the clutch pedal from neutral position until the brake pedal is released, and under such conditions over coming any possibility of the actuation of the clutch pedal to prevent stoppage of the car on the application of the brakes from the brake pedal.

Further objects of the invention areto provide, in a manner as hereinafter set forth, a safety device for the purpose referred to, which is simple in its construction and arrangement, strong, durable, thoroughly efficient in its use, convenientlyinstalled, and inexpensive to manufacture. With the foregoing and other objectsi view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically de:

scribed and illustrated in the accompany ing drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like refer ence characters denote corresponding partsthroughout the several views;

to a safety device;

A safety device, in accordance with this "OFFICE.

invention, comprising a'base plate 4 formed of a reduced upper part 5 and a tapered lower vpart 6. r The part '5 is of greater length- -than the part 6 and is attached to be adjustably positioned against the upper The plate 4. is I.

formed with a pair of lengthwise extending slots 7, Sarranged out of alignment with respect to each other. The slot 7 isopen at its upper end and arranged at the upper portioniof the j'part'5 of the plate. The

slot 8'is closed at eachend and is positioned at the lower portion of the part 5. Carried by the upper foot board 9 are bolts 10 which extend through the-slots 7 and'8 and carry wing. nuts 11 engageable with the upper face of the plate 4 for the purpose of clamp- 1ng it against the foot board 9. The slots 7, 8; bolts 10; nuts 11 provide means where'- by "the plate 41 can be adjustably positioned on the upper foot board 9, as well as being detachably-clamped thereto. The part, 6, after the 'plate i has been adjustedfls fixedly secured by the holdfast device 12 to the lower foot board 13. The plate 4 is positioned in proximity to one side of the-clutch pedal-1 and projects above the slots 14 and I through which extend the pedals 1, 2 and 3. The plate 4 in proximity to thelower part;

6 thereof,hasfixedly secured to thehouter face thereof, by the holdfast devices. 15, a

pair of rectangularplates 16, each formed;-

at-itslowerv side with, a guide barrel 17 disposed transversely with respect to theplato 4. The guide barrels 17 are arranged in alignment and theinner ends-thereof are spaced from each other and mountedin the barrels 17 is a slidable locking bolt 18, of

. a head 21. Secured to the disk 21 anddepend- Figure 2, is a section online 2 -2, Fig-- ing'therefrom is a lever arm 22 provided. at its lower end with a yoke 23 which straddles the reduced portion 19 of the bolt 18. The upper. end of the lever arm 22 is reduced, as indicated at 24 thereby providing a shoulder 25. The reduced upper end 24 of the lever arm 22 is peripherally, threaded and engageswith thethreads formed'flon the wall of a socket 26 provided in the disk 21.

Connected to the disk 21 and extending. substantially at right angles with respect to the lever arm 22, is a lever arm 27:, of greater length than the arm 22. The inner end of the arm 27 is reducedas at 28'-.and.has-

threaded engagement with the wall of a socket 29rformed in r the disk 21 substantially atirightangleszto the socket26; The out-' er' endgof the lever arm 27*isformed with a rightangularly disposed upwardly projecting; extension: 30. The lever arm27 eX tendstoven the several clutch pedals toa pointslightly beyond the-brake I pedal 3:

The-brake pedal 3 is formed with an opening 31- through which extends a projec tion 32* formed integl'al w-ith and at right angles-Lto the: lower end of an A upwardly-"extending-bolt 331 The projection 32" hasitsfree endextended from one'sideof the' brake pedal 3' and is connected-tether latter by; a cotterpin 34-whichis mounted in the projection '32 interiorly ofth-e pedal 3; The bolt 3'3 is positioned on' the; outer side of' the brake pedal I 3" and has mounted on its upper threaded terminal portion a turnbuckle 35,

which threadably engages with the threaded lower terminal= portion of: an eye-bolt 36,

The head 37'of the bolt 36 is in the form-of an eye and projecting throughthevsame-is the-extension 30. The extension30 isconnectedto the-head 37 by a cotter pin 38. A stop nut 39 is carried by this-bolt 36 above the turnbuckle 35. V

The bolt- 18, whenslid to active position,

is arranged in the; pathof the clutch pedal;

1, to prevent the latter -frombeing-sh-ittecl from neutral and'the-arrangement of the device with respect to the clutch; and brake pedals-is such that, under 'normal condi tions, the various elements of the device will be as illustrated infull linesin; Figure 1-,

but onthe applicationofbrake pedal, the

lever arms 22*a-nd 27will-be shifted'to the dotted I line posit-ion -'sho wn in Figure 1', and when-moved tosuch positions,'the lever-arm 22' will slide the bolt 28 to' the-'dotted-line position-shown-in Figure 1 and-which will posed a substantialldistanoe vabove the-pedals 1, 23and-3 so'as-not to interfere in any-mam nerwiththe action thereof. The provision for the adjusting of the plated on the upper foot: board '9 enables the positioning ofthe device in a proper manner to accommodate tight; or loose brake bands. The turnbuckle 35, in connection with the threaded bolts 33, andv 36, provides meansfor adjusting the throw of the lever arm 27- and the stop nut 39 provides means for maintaining the turnbuckle in usted. position.

It is to be understood that any suitable form of, locking bolt, with its support, can be employed. The construction shown is thepreferableone. It is furthermore to be understood that in lieu of employing the coupling device, as showmbetween the elements 3 and 27, a coiled springcould; be substituted.

Iti'sthought that the many advantages of safety: device, invaccordance with this invention, and; forv the purpose set forth,

can be: readily. understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be-understoodthatchanges:in the details of construction can be had& which fall within the scope of the invention as claimed.
